[Thinkpad] High Power USB Port

[Rob Bell]

One can get a dual-ended USB cable that allows the drive to draw power 
from two USB ports.  Often the USB drive enclosures come with these 
types of cords.

Be aware that you can trash a disk if you try to run it in an external 
enclosure with too little power.  I toasted a 2.5" laptop drive this way 
a month or so ago.
